I'm right there with you, Shooting Star. My father is at the end stage of prostate cancer. His wife called us kids yesterday and told us to come see him now because he doesn't have long, maybe a week or two. I was just there week before last, but I'll be heading back on Thursday.
There's a lot that can be done to make your dad more comfortable. Look into hospice. They've been a godsend for my father and his wife. Truly.
Much love to you and our family,
Roxy
